Application filed August 22, 1914. Serial No. 858,082.

To all 20/1 am. it may concern Be it known that I, Janus DIFJ-ENBACKER, a citizen of the United States, residing at Burrows, in the county of McKean and State of Pennsylvania, have invented new and useful Improvements in GlassMachines, of which the following is a specification.

The invention relates to a production of a machine for making wire glass, constructed particularly with a view to prevent the usual cold ends of the sheet of glass after it is rolled.

The main object of the present invention is the provision of a wire glass machine including a steel roller which receives the material from the hopper and which is specifically formed to properly distribute the glass with respect to the wire strip, the distributing elements of the roller being formed to prevent the metal sticking therein during operation.

The invention in the preferred form of details will be described -in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a longitudinal sectional view through the machine. Fig. 2 is a front elevation of the same. Fig. 3 is a top plan view. Fig. 4 is an enlarged development of the forming roller, a portion only of the same being shown.

In the preferred embodiment of the details of the present machine, 1 represents the usual table at the respective side edges of which are secured uprights 2. Bearing blocks 3 are slidably adjustable in the uprights through the medium of screw rods 4: and nuts 5, as is usual for such adjustment. A. forming roller 6 is rotatably sup ported in the blocks 3, said roller having a series of channels 7 extending longitudinally thereof, the channels opening through the ends of the roller, as is clearly apparent fromthe drawing. The forward and rear Walls, so called With respect to the direction of rotation of the roller, of the slots have different degrees of curvature, the forward Wall having sucha degree of curvature that its projection beyond the straight line joining the terminals of said Wall is one-thirtysecond inch, the similar curva-.

ture of the rear wall being 1/16 inch. 'At their inner ends, the side and end Walls of the channel are spaced apart a distance approximately 1/16 inch in width, while the distance at the free or peripheral edge of the roller between adjacent channels is 1/ inch. These dimensions are approximately correct for a full sized operative roller, though it is understood that they are stated to indicate more particularly the relative proportions, the exact size being variableas may be required.

Supported upon a platform to the rear of the roller is a hopper 8, open at the top and having front and rear walls on different radii so that the delivery end or? the hopper is in effect the apex of the tri-angular shaped element. The apex 9, which constitutes the delivery end of the hopper, un-

derlies the forming roller slightly in rear of the point of minimum spacing of said roller from the table. Supported above the hopper are rolls 10 and 11, the former con stituting a guide roll and the latter tension or pressure roll. The guide roll is rotatably supported in arms 12, while the tension roll is'rotatably supported in arms 13 pivotally mounted on the arms 12, and connected with thelatter above the pivotal connection by spr ngs 14, whereby the pressure roll is maintained in contact with the guide roll;

The strip or section of wire mesh 15 is fed over the guide roll beneath the tension roll and to and beneath the 'iorming'roll. The molten metal or glass is poured into the hopper and passes beneath the forming roll where bv reason of the channels a suffi cient quantity of said glass is forced above the wire strip to centrally position the latter in the mass, so that as the plate thus formed passes beneath the smoothing roll (not shown). the upper section of glass, that is the portion above the wire strip will equal that portion below the same.

By reason of the delivery of the metal immediately adjacent the forming roll, to gether with the projections formed by the channels, it is obvious that the cold end of the glass will be cut or forced from the body during forming operation, and that furthermore, the peculiar formation of the walls of the channels of the forming roll will prevent the possibility of the glass sticking in said roll during rolling operation.

What is claimed is 1. A wire glass forming machine including a forming roller having a series of longitudinal channels therein, said channels presenting grooves having an entrant opening of maximum width from which the groove gradually narrows to the apex, the opposing side walls of the groove being on slightly difierent radii, the groove having an inner squared wall approximately at right angles to a radial line of the roller,

2. A wire glass forming machine including a table, a forming roller adjustably mounted above the table and formed with a series of longitudinal channels, and a hopper for delivering material immediately adjacent-to the space presenting the minimum distance between said roller and table.

3. A wire glass forming machine including a table, a forming roller adjustably mounted above the table and formed with a series of longitudinal channels, a hopper for delivering material immediately adjacent to. the space presenting the minimum distance between said roller and table, and

means for guiding a wire strip to the form-
